Title: Improvements in rakes
IPC: A01D76/00
Filed: 1935-07-01
Abstract: 459,147. Hay-rakes. BAMFORD, J., St. Mary's Mount, and BAMFORD, C. J., The Parks, both in Uttoxeter, Staffordshire. July 1, 1935, No. 18780. [Class 6 (iii)] A field rake of the type in which some or all of the tines are mounted on a swinging frame in such manner that they can make a lateral folding movement substantially parallel to the axle whereby the distance between adjacent lines or adjacent groups of tines is decreased during the folding movement and wherein the length of the axle can be reduced is provided with a lever or member which can be operated by the driver to put into operation means actuated by the road wheels for raising the tines to release the crop. The machine comprises ground wheels 1, each rotatably mounted upon an axle length 2. Each axle length slides into a sleeve 3, forming part of the main draught frame 4, being secured in adjusted position by screws 5. The tine carrying frame comprises a centre part of fixed length having end members 6 rotatably mounted on the axle members 2, and connected together by a sleeve 8 that forms an extended bearing for a pair of sliding rods 9 of noncircular section, and two end parts of variable length. Each end part comprises an end member 10 fixed to an axle 2 and connected to one of the members 6 by a rod 9 that passes through and is fixed to a bush 11 arranged for rotation in the member 10. The parts 6, 10 are also connected by a second rod 17, fixed at one end to the member 10, and provided with a screwed portion, and nuts 18, 19 by which the distance between the two parts may be adjusted. The end of each rod 9 is cranked to engage a pawl 22 adapted to engage the teeth of a ratchet wheel 24. The crank is rocked to engage the pawls by turning the sleeve 8 and so the rod 9 by the depression of a foot lever 25 connected by a link 27 to a lever 28 secured to the sleeve. When the pawls are engaged the swinging frame including both the centre and the end portions is swung about the axle to lift the tines. Cams throw out the pawls after the tines have been lifted sufficiently. The tines may be retained in the raised position by a catch. The tines on the end parts are carried by lazy tongs 41. Band-brake mechanism may replace the pawl and ratchet teeth. Instead of a pedal a hand lever or Bowden cable mechanism actuated by the attendant on a tractor may be used. All the tines may be arranged to close together, and the fixed section of tines may be arranged at the end of the rake instead of in the middle. Specification 358,629 is referred to.

Title: Unsubstituted and substituted guanylurea salts of penicillins
IPC: C07D499/24
Filed: 1950-07-27
Abstract: Unsubstituted and substituted guanylurea salts of penicillin are prepared by reacting a penicillin or a penicillin salt with an unsubstituted or substituted guanylurea or an acid salt thereof. Preferably the salts are used, e.g. sodium or potassium penicillin (or other penicillins), amine penicillins such as triethylamine penicillin, and the hydrochloride, sulphate, nitrate, phosphate or acetate of the guanylurea.  The reaction is carried out in the presence of an inert solvent such as water, alcohol, aqueous alcohol, acetone or other ketone.  Specified substituted guanylureas are alkylguanylureas, e.g. methyl, butyl, octyl or dodecyl guanylurea penicillin; aromatic and aliphatic acyl guanylureas, e.g. benzoylguanylurea penicillin; aryl and haloaryl guanylureas, e.g. p-chlorophenyl guanylurea penicillin, phenyl guanylurea penicillin and N1,N5-bis-(p-chlorophenyl) guanylurea penicillin; a carbamyl guanylurea penicillin and N-pentamethylene guanylurea penicillin. The guanylureas may be prepared according to Specification 631,878. n-Octyl-guanylure neutral sulphate dihydrate is prepared by heating n-octyldicyandiamide with concentrated hydrochloric acid in the presence of dioxane.  The dioxane is removed, water added and then sodium sulphate.  The unsubstituted or substituted guanylurea salts of penicillin may be used in the separation and purification of penicillin, or as a medicine (see Group VI).

Title: Method of and apparatus for carrying out chemical reactions
IPC: B01J19/08
Filed: 1948-07-14
Abstract: The zone in which chemical reactions are carried out, under conditions of temperature and pressure normal to the reactions, is subjected to the influence of crossing fluxes produced in a place at right angles to the horizontal component of the earth's magnetic field, each of the fluxes being produced by a silent electric discharge across two opposing pointed electrodes having a potential diffierence of 1,000 to 160,000 volts derived from a source of direct current, the reactants being outside the paths of the fluxes. Examples relate to the saponification of tri-stearic with super-heated steam, the production of cement and the reduction of iron and aluminium ores, the reactions in each case being carried out in reactors which, according to their position, are 3 to 60 metres from the apparatus producing the fluxes, such apparatus having been in operation for 20 days before the reactions are commenced.ALSO:Cement is produced under normal conditions in kilns which are subjected to the influence of crossing fluxes produced in a plane at right angles to the horizontal component of the earth's magnetic field, each of the fluxes being produced by silent electric discharges between two opposing pointed electrodes having a potential difference of 1,000-160,000 volts derived from a source of direct current, the cement kilns being outside the paths of the fluxes.  The apparatus for producing the fluxes is operated continuously for twenty days before cement making is commenced, the reaction time then being reduced from 2 1/2 hours to one hour.

Title: Manufacture of acetyl-cellulose in the form of bands or threads
IPC: D01F2/28
Filed: 1929-06-20
Abstract: 313,974. Wacker Ges. f³r Elektrochemische Industrie Ges., Dr. A. June 20, 1928, [Convention date]. Right to Patent relinquished. Cellulose acetates, and processes for making filaments and films therefrom.-Artificial silk threads or bands are made by extruding primary solutions of cellulose acetate prepared as described in Specifications 291,001 and 325,209 into precipitation baths. In an example cotton linters are acetylated in a bath containing zinc chloride, glacial acetic acid, and acetic anhydride until complete solubility in chloroform is obtained. The excess of acetic anhydride is then decomposed and sufficient aqueous hydrochloric acid added to correspond to the formation of ZnCl2.HCl.2H2O. The product is saponified until it is soluble in acetone, whereupon sodium acetate is added to convert the zinc chloride into zinc acetate and the solution is then worked up, either as it is or after suitable dilution, by the wet spinning process. The solution may, however, be allowed to stand, even for days, without any adverse effect on its viscosity or the tensile strength of the product.

Title: Jointing or terminating plastics sheathed electric cables
IPC: H02G15/10
Filed: 1975-05-06
Abstract: 1504524 Jointing or terminating cables BICC Ltd 5 May 1976 [6 May 1975] 19015/75 Heading B5A An electric cable C is jointed or terminated by locating a longitudinally split plastics sleeve 1, of, for example, polythene, over the cable adjacent the joint on termination. The sleeve is internally supported by a two-part rigid tube 4 and the edges 2 of the sleeve adjacent the or each split are chamfered to define a groove 3 of V-shaped cross-section. A mould 5 having an elongated groove 6 is clamped by bands 8 with the groove 6 located over the groove 3. Feed and discharge ports are provided in the mould which communicate with the groove 6. In use, molten plastics, for example polythene, is introduced through alternate ports, this being continued until the plastics exudes from the other ports. The feed is then terminated and the plastics is allowed to cool, any shrinkage being accommodated or by lowering plungers within some of the ports. After solidification, the mould and support tube are removed and the sleeve moved into position over the joint or termination where it is welded to similar perhaps non-plastics, sleeves to complete the jointing or terminating operation. It may be necessary to preheat the mould and the groove in the sleeve to initially soften the groove by introducing hot gas into the mould prior to the introduction of plastics material. It is preferred for the mould and support tube to extend beyond the ends of the sleeve, any projecting plastics material being cut off before the sleeve is moved to its final position.

Title: Improvements in or relating to electric current converting systems comprising vibratory relays
IPC: H02M7/62
Filed: 1943-11-18
Abstract: 574,428. Converting. HARMER, H.M., and COOK, F. J. Nov. 18, 1943, No. 19248. [Class 38 (ii)] [Also in Group XXXVII] In a converting arrangement of the vibrating switch type, use is made of a plurality of vibratory relays of the kind in which frequency varies with amplitude, one relay controlling the frequency of the others. In the arrangement shown, two relays VA, VB have their associated drive coils DA, DB so connected and arranged that the relays operate at the same frequency, but with a 90 degree phase displacement, the relay VB short-circuiting the drive coil DA when it is attracted by its own coil DB whilst the relay VA short-circuits the drive coil DB after release by short-circuiting of its drive coil DA. Thus, the two transformers TA, TB are energized with a 90 degree phase displacement and their outputs when rectified by rectifiers RA, RB overlap to produce a substantially steady D.C. Modifications in which the drive coils are energized through separate contacts associated with the vibratory elements, and in which the rectifiers RA, RB are replaced - by additional contacts on the relays are described. Specification 554,712 is referred to.

Title: Digital error control systems
Inventor: BURTON HERBERT O
IPC: H04L1/00
Filed: 1966-05-03
Abstract: 1,144,700. Data transmission systems. WESTERN ELECTRIC CO. Inc. 3 May, 1966 [7 May, 1965], No. 19416/66. Heading H4P. In a digital transmission system in which errors are corrected by repetition each data word comprises a number of check bits to enable the detection of errors, and further information is sent by modification of the check bits. The input to the transmitter and the output of the receiver are at a steady rate in spite of repetition cycles. In the embodiment described 4-bit input signals from a buffer store have added to them 8 check bits and 4 dummy bits, normally " 0 " bits. The resulting 16-bit words are sent at four times the bit rate of the input signals. If an error-indicating signal is received from the distant station the next check bits to be sent are modified by modulo 2 addition of an 8-bit word and the dummy bits are sent as " 1 " bits. There follows a repetition cycle comprising the last 5 words in the buffer store. The twenty words following the modified word are 12-bit words, no dummy bits being sent. At the receiver the 4 information bits are stored and also pass to a circuit which generates 8 check bits which are compared with the 8 check bits received. If they are not identical an errorindicating signal is returned to the transmitter and the faulty 4-bit signal and the next four received signals are cancelled from the store; among these is the signal which had the modified check bits. A counter detects the dummy 1 bits and increases the cycling rate of the receiver to correspond to the 20 shorter words now to be received. The receiver store has sufficient capacity to permit a steady stream of unmutilated data to the output. If the transmitter receives an error-requesting signal although none was sent by the receiver, the transmitter provides signals as specified above. The receiver detects the presence of the modified check bits and, because no error has been detected in the last 4 words, recognizes the modified signal as heralding an unrequested repetition. It therefore cancels from the store the 4-bit signal accompanying the modified check bits and the next four signals, the latter being the undesired repeated signals. The end of message signal is indicated to the receiver by modification (by modulo 2 addition) of the check bits of the last word to be transmitted. This modification, on being detected at the receiver, causes the receiver to be set to quiescent.
